Lookin at those diagrams I guess the upper right would be the one to use, with one exception. Where it shows the wire going to the switch don't worry about making that connection to the fuse/battery. Your connection to the switch from the battery is already made. The wire that is on your stock horn will connect to 86 and connect a ground to 85. 30 is always from the battery and 87 always goes to the load (Horn). If the horn is metal and you mount it to metal you may not need to run a ground, but i would plan on one anyway. I'd plan on using 14 or 12ga stranded wire. You can get a fog light relay 30A at autozone or pepboys. Hope this helps.
PS Looks like Stebel might be the manufacturer of your BOLO horn. They look an awful lot alike.
